Would anyone know the ancestors of Susan Blue (b. 1817) who married Isaac Parsons (1814-1862). Susan Blue's father was Garrett Blue (b. 1790-after 1860). Who was Susan's mother? Who were Garrett Blue's parents? Also: There was a Grace Blue who married Louis Brady Brydon (1876-1929) of Bloomington, Garrett Co. Md. Was Grace Blue connected to Garrett Blue's family? Thank you for your assistance. Jean
